ある。 The present invention aims to prevent the destruction and abrasion of the road surface and the generation of dust associated with it by configuring the spike pins so that they can be stored inside the tire when not needed. Focusing on the fact that the heat generated by the road changes depending on the frozen and snowy conditions of the road, its feature is that the protruding state of the spike pin can be automatically changed according to the frozen and snowy conditions of the road. It is.

位置とに変形可能に構成している。 That is, the spiked tire of the present invention is provided with a spike pin that can freely protrude and retract from the ground contact surface of the tire body and a guide pin that supports and guides the spike pin, and a flange portion provided on these spike pins and the guide pin. Flat support surfaces facing each other and tapered guide surfaces connected to the support surfaces are formed, and between these flange parts is a shape memory whose properties change depending on temperature between a state of deterioration and a state of restoration to the memorized shape. An alloy actuating member and a spring that compresses and deforms the actuating member in a flexible state are provided, and the actuating member is fitted between the tapered guide surfaces and between the support surfaces by the biasing force of the spring. It is configured to be deformable into an actuated position in which the spike pin is held in a protruding state and an inoperative position in which it escapes from between both supporting surfaces and holds the spike pin in a retracted state by restoring to its memorized shape. There is.

置をとるように構成している。 A ring-shaped actuating member 9 made of a shape memory alloy whose properties change depending on temperature between a fragile state and a self-recovery state to a memorized shape is disposed between the flange portions 5 and 6. A spring 10 is disposed to compress and deform the actuating member 9 in the above-mentioned state, so that the operating member 9 is caused to contract in diameter along the guide surfaces 7 and 8 by the biasing force of the spring 10 when the actuating member 9 is cooled. By pressing the spike pin 3, the flanges 5 and 6 are separated, and the support surface 5
The spike pin 3 is inserted between the support surfaces 5a and 6a to take the operating position shown in FIG. 2, in which the spike pin 3 is held in the recessed state in the embedding hole 2, as shown in FIG.

によつて埋込穴２内への没入状態に保持される。 When driving on a frozen or snowy road using a spiked tire having the above configuration, as shown in FIG. The flange portions 5 and 6 are compressed and deformed by the urging force and are separated, and are fitted between the support surfaces 5a and 6a to hold the spike pin 3 in a protruding state. On the other hand, when driving on a road that is not frozen or covered with snow, the actuating member 9 is heated mainly by the frictional heat between the road surface and the tires. It returns to the enlarged diameter state by itself against the urging force of the spring 10 and escapes from between the supporting surfaces 5a and 6a. Therefore, the spike pin 3 is held in a recessed state in the embedding hole 2 by the elastic restoring force of the tire body 1.

とができる。 As described above, according to the present invention, the spike pins can be automatically made to appear and disappear depending on the frozen or snowy condition of the road, thereby ensuring safe driving in the frozen or snowy conditions, and at the same time, preventing the road from freezing. It is possible to reliably prevent road surface destruction and abrasion, as well as the generation of dust associated with this, even when there is no snowfall. Moreover,
An actuating member made of a shape memory alloy is fitted between the flat supports provided on the flanges of the spike pin and the guide pin, thereby holding the spike pin in a protruding state, so that it can withstand the heavy loads of the car. Also, the spike pin can be supported reliably.

A tapered guide surface continuous to the support surface is formed, and an actuation member made of a shape memory alloy whose properties change depending on temperature between a state of deformation and a state of restoring to the memorized shape depending on the temperature; and the actuation member. A spring is disposed to compress and deform the spike pin in a flexible state, and the actuating member is fitted between the tapered guide surfaces and between the support surfaces by the biasing force of the spring, thereby holding the spike pin in a protruding state. A spike tire characterized by being deformable into an active position in a neutral state and an inactive position in which the spike pin is held in a retracted state by being released from between both supporting surfaces by restoring to a memorized shape.
